PAPER BAG.

SPECIFICATION forming part of Letters Patent No. 426,607, dated April29, 1890. Application filed January 31, 1890. SerialNo. 338,'292. (Nomodel.)

T @ZZ whom,` it may concern:

Beit known that I, JOHN SINGLE, of Syracuse, in the county of Onondaga,in the State of New York, have invented new and useful I1nprovements inPaper Bags, of which the following, taken in connection with theaccompanying drawings, is a full, clear,` and exact description.

My invention relates to an improved paper bag, and has for its objectthe production of a simple and effective construction which can bequickly and economically assembled; and to this end my inventionconsists, essentially, in a blank having the edge of its bottom or topand bottom out with a series of steps one above the other, two of whichsteps are preferably formed on the portion of the blank designed foreach side, and the remaining steps on the portion composing the frontand back of the bag, and in folding over the bottom of said bag upon itsbody, whereby each of the said steps contact with the portion upon whichthey are folded, thereby enabling paste or other adhesive material tosecure each of said steps directly to the body of t-he bag.

In describing this invention reference is had to the accompanyingdrawings, forminga part of this specification, in which like lettersindicate corresponding parts in all the views.

Figure l is a plan view of the preferable form of blank from which myimproved bag is constructed. Fig. 2 is a plan of the detached end of theblank, illustrating the separate steps thereof and showing by a dottedline the line upon which the bottom is folded. Fig. 3 is a like planview with the bottom of a blank of the construction illustrated in Fig.2 folded upon itself for completing the construction of the bag. Fig. etis an isometric perspective of the blank as seen in plan in Fig. 2. Fig.5 is an isometric perspective of the completed bag. Fig. 6 is a plan ofa modified form of blank having a portion thereof broken out. Fig. '7 isa top plan view of the detached end of a bag constructed from said blankand illustrating the bag before the filial operation of folding thebot-tom upon itself 5 and Fig. S is a like view to Fig. 7, illus tratingas completed the final operation of folding upon itself the bottom ofthe bag.

A represents the blank, which may be of suitable size, form, andmateriall best adapted of paper bag. As illustrated, the lower edge 4CLof the blank is formed with a series of steps d, l), b', and a2, onebelow the plane of the other, and the portions of said blank having thesteps a and a2 at their edge are adapted to form the front A and back A2of the bag. The sides B are what are termed bellows sides, and areformed by bending them i3nwardly at the center h2, as best seen in Fig.4.

By reference to the (ilrawings, particularly Figs. l and 4;, it will benoticed that the bottom edges of the sides B are provided with the stepsb and b', which extend from the outside edges to the center line h2, andare preferably in planes one above the other.

rThe portion of the blank for forming the back of the bag is hereillustrated as divided in its central part and adapted to have its edgesa3 pasted together; but it will be understood that this lapped portionmay be located at the front or at either of the sides,al though theillustrated way is preferable.

After forming the bag, as illustrated in Fig. 4c, by pasting togetherits longitudinal edges a3, the sides are bent inwardly into the positionillustrated in Fig. 2, whereupon it will be noticed that the steps ofthe front, back, and sides are one above the other, thereby enablingpaste or other suitable adhesive niaterial to be brushed or wiped uponeach step by a single movement crosswise of the end of the bag withoutnecessitating the insertion of the brush between any of the parts, as isthe case when two or more of the edges of said parts are in the sameplane.

After the bag is formed, as illustrated in Fig. 2, and the paste isplaced thereon, the bottom is folded upward from the dotted linecc'1,which is a sufficient distance above the top step a ofv the bag,whereupon it is evident that a slight portion of the front, back, andsides will rest against the body of the bag and produce a very strongconstruction of bottom, which, as previously set forth, may be pastedwith great rapidity, since but one moven ment is required.

After forming, as described, the bottom of the bag may be squared, asshown in Fig. 5, whereupon it may then be refolded and is in conditionfor shipment and sale.

As seenin the drawings, in order to econo careful handling in pasting.

mize 'the amount of paper required in cutting the bag, and to enable onecut to form the top of one bag and the bottom of the other, I prefer toconstruct the top of the same shape as the bottom, and this presents uare folded as shown in Fie. l it is onlv necessary for the operator toplace the steps so as to be supplied with paste, and it makes nodifference which end of the blank he pastes.

At Figs. G, 7, and 8 I have shown a modified form of my bag, in which,instead of forming'the edges of the sides of steps in sep arate planes,the said edge is cut slanting from the top to the bottom of the sides,thereby effecting the same result; but it is evident that thisconstruction is not as desirable, as it does not produce as strong abag, since there is not as much surface to which the paste may adhere.

Theoperation of my invention willbe readily perceived from theforegoing, and it is evident that a bag constructed as aforesaid is veryquickly and economically man ufactured, and possesses a stronger andmore efficient bottom than bags as ordinarily constructed, which is afeature of great advantage, greatly increasing its sale anddesirability. It is evident, however, that the described construction ofbag may be somewhat'varicd without departing from the spirit of myinvention.

Having thus fully' described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

l. The herein-described blank for paper bags, the same having one edgeformed with a series of four steps, one above'the other, the portionshaving the highest and lowest steps being adapted to form the front andback of the bag, and the intermediate portions having the remainingsteps being adapted to form the bellows sides of the bag, substantiallyas specified.

2. rlhe herein-described blank for paper bags, the same having its topand bottom edges provided with a series of four steps, one above theother, the portions having the highest and lowest steps being adapted toform the front and back of the bag, and the intermediate portions havingthe remaining steps being adapted to form the bellows sides of the bag,substantially as set forth.

3. The herein-described bag having the edge of the front and back sidesin separate planes and having bellows sides folded inwardly, with theedges of the separate folds of each side out of the plane of and betweenthe aforesaid edges, and also out of the plane A of eachother, and aportion of said front and back sides and the bellows sidesbeing foldedover and pasted upon the body of the bag, substantially as set forth.

In testimony whereof Ihave hereunto signed my naine, in the presence oftwo attesting witnesses, at Syracuse, in the county of Onondaga, in theState of New York, this 21st day of January, 1890.

JOHN SINGLE.
